SPECIFICATION forming part of Letters Patent No. 648,021, dated April 24, 1900.

' Aspiration filed November 22,1899. Serial No. 737,912". (No time.)

To It whom it may concern:

Be it known that I, JOHN W. D. OARSLAW, a subject of the Queen of Great Britain, residing at Chicago, county of Cook, State of Illinois, have invented a certain new and useful Improvement in Tires; and I declare the following to he afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention has for its object the production of a fastening device for rubber tires on vehicles, &c.; and it consists in a combinationof devices and applianceshereinafter described and claimed. I

In the drawings, Figure 1 is a cross-section of a wheel-rim tire and fastening device. Fig. 2 is an enlarged side elevation of a section of the fastening-strip. Fig. 3 is a cross-section of the fastening device.

In carrying out the invention, A represents the rim of the wheel, 13 the channel-iron engaged to the rim in any suitable manner, and C the rubber tire.

D isa strip of metal (shown in cross-section in Fig. 3) having a web portion cl and a head or bead d. On each side of the tire isaridge or bead 0, located when the tire is in place about on a line with the edge I) of the rimchannel, although this particular location is not essential. In engaging the tire to the rim the tire is first sprung into place, with the tire substantially filling the channel-iron. The strips D are then forced into place, with the web 61 passing down between the tire and the flange b of the channel-iron, the lower edge preferably, although not necessarily, entering and resting in a groove b in the channeliron. This brings the head cl to a bearing against the bead c on the tire. The ends of the strip D are then fastened together in any suitable manner-as, for instance, by weldingand there being a strip for each side of the tire the latter is'held firmly in place.

In order to give the strip D the desired curved shape, theweb may be slitted, as at 01 although this might not be necessary, as the curved shape might be given in the rolling. It is obvious that the specific shapes in cross section of the head d and of the bead c are immaterial, although I perfer about the form shown.

The material advantage in a fastening device such as mine over one that passes through the tire is that the rubber is not weakened, and consequently will not tear out. Again, by the provision of the web 01 a broad surface of the fastening device is presented to the rubber, so that the fastening device will not cut into the rubber.

By extending the edge of the web into the groove 1) the edge is prevented from cutting into the rubber.

What I claim is'- 1. In combination a rubber tire and a wheel rim having projecting flanges between which the tire is seated, said tire provided on each of its sides with a continuous ridge or shoulder, said tire held in place by two retaining strips, one for each side of the tire, each of said strips provided with a ridge or projec= tion adapted to be drawn down against the ridge or shoulder on the tire and thus com= press the tire in its seat between the rim flanges, the ends of each strip being fastened together after the strip has been drawn into place, substantially as described.

2. In con1bination,a rubber tire and awheelrim having two projecting flanges between which the tire is seated, a continuous shoulder or projection along each side of the tire, said shoulders when the tire is in place being adjacent to the edges of said projecting flanges and a fastening-strip for each side of the tire consisting of a strip of metal having a web portion adapted for insertion between the tire and the rim-flange, said strip provided along the edge of the web portion with a projection adapted to bear on the ridge or shoulder on the tire, and. thus compress the tire in its seat between the rim-flanges,the ends of each strip being fastened together after the strip has been drawn into place, substantially as described.

3. In combination a rubber tire and a wheelrim having two projecting flanges between which the tire is seated, each side of the tire being provided with a rounded. seat or projection located when the tire is in place opposite the edge of the adjacent rim-flange and a retaining-strip for each side of the tire consisting of a web portion provided on its edge with a rounding projection adapted to fit the shoulder on the tire, said projection when the tire is in place being substantially opposite the edge of the rim-flange, and thus compress the tire in its seat between the rim-flanges the ends of each strip being fastened together after the strip has been drawn into place substantially as described.

4. The combination with a rubber tire and the wheel-rim, of a continuous ridge or shoulder alo'n g each side of the tire, an outwardlyextending flange on each edge of the rim, be-

tween which the tire lies, and two fasteni ng- 15'
